This invention'relates to the manufacture of car wheels, and has for its object broadly the provision of a carwheel of new and improved construction and a process for the manufacture of said car wheel. v

A principal object of the invention is the provision of a car wheel of equal. strength and lighter in construction than those usually heretofore provided.

My invention contemplates the perforation of the web of the wheel without corresponding weakening of the construction and to this end I provideas an incident to such perfora- Y tion an outstanding reinforcing rib on one drawing the metal either within or withoutv 0r both sides `of the web and about such perforation, such rib being formed by upsetting or the area of the perforations. Y

Another important object of the invention is the provision of a car wheel having its central hub and peripheral flanged rimvconnected by integral spoke parts of strengthequal to or greater than the strength of acontinuous unperforated web. In such event' the material of the web located between them- Y tended spokes is preferably drawn or upset into outstanding reinforcing ribs about' the apertures defining the spokes.

Another'and highly important object of the invention is the elimination or at least the vminimizing of the danger of the cracking of the web of rolled steel car wheels as an inci-Y j,

dent tov their cooling and this without reduc- Y ing the strength of the resulting wheel. I

v c rate the web of rolledsteel car rwheels to pre` `vent cracking in cooling but heretofore said danger of cracking.correspondinglyreduced.

am aware that it has been proposed to perfoperforation has correspondingly weakened the web. In providing reinforcement about suchV perforation, whatever-be its shape, the usual or increased strength is maintained and Numerous other objects and advantages of the invention will be readily understoodk from the followingv description which, when taken in connection with the accompanying draw-l ings, illustrates aa preferred embodiment thereof.
